{"cve":"CVE-2026-4244","nvd":{"published":"2026-08-22T13:16:37.523","modified":"2026-10-12T16:10:00.220","status":"Deferred","description":"The Post Duplicator plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the `duplicate_post()` function in all versions up to, and including, 3.0.11. This is due to the function not verifying that the user has `edit_others_posts` capability before accepting a `selectedAuthorId` parameter via the `duplicate-post` REST endpoint. This makes it possible for authenticated attackers, with Contributor-level access and above, to create duplicated posts attributed to any user, including administrators.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","score":4.3},"cwes":["CWE-862"],"references":["https://plugins.trac.wordpress.org/browser/post-duplicator/trunk/includes/api.php#L520","https://plugins.trac.wordpress.org/browser/post-duplicator/trunk/includes/api.php#L550","https://plugins.trac.wordpress.org/browser/post-duplicator/trunk/includes/api.php#L728","https://plugins.trac.wordpress.org/changeset/3485579/","https://www.wordfence.com/threat-intel/vulnerabilities/id/64553742-ff2b-40e9-92c3-3458a9f988a2?source=cve"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:49:38.260478770+00:00"},"epss":{"cve":"CVE-2026-4244","score":0.00336,"percentile":0.26761,"date":"2026-10-25"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
